           Summary: assignment in return when using cdouble is broken
           Product: D
           Version: 0.172
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Keywords: wrong-code
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: baryluk at mpi.int.pl


Minimal test case:
-----------
cdouble y;

cdouble f(cdouble x) {
    return (y = x);
}

void main() {
    f(1.0+2.0i);
    assert(y == 1.0+2.0i); // asseration fails on dmd 0.166-0.172
}
----------


If I'm using double instand of cdouble, or rewrite f as:
---------
cdouble f(cdouble x) {
y = x;
return x;
}
---------
then it's working ok.
